My advice - have the flat bar over length by a couple of inches either side - clamp it up against the bottom of the chassis (i.e. - where the floor will go) then you can play about shifting it nearer to / further way from the transmission tunnel - if required. I certainly had to tweak my seat side-to-side - so actually laid it all up on a piece of chipboard clamped to the bottom of the chassis - and marked it all up before cutting the flat bar.... That also meant I could remove the seat fully to keep it safe from spatter before welding.
